Don't let those hard-earned watts vanish into the ether with excessive drivetrain friction, causing drag at every speed, and instead invest in the Oversized Pulley Wheel System from CeramicSpeed and enjoy a reduction in power expenditure while cruising at the same speed or going faster with the same effort. It's typically harder to quantify frictional losses compared to say, aero data in the wind tunnel or grams on a scale, but if you are looking for every high-performance advantage available and don't want any excuse with your equipment on fast training rides and come race day, ceramic bearings in larger diameter derailleur pulleys is a worthy upgrade.
